Explanation of Responses:

Id	Content
F1	Each share of Class B common stock held by the Issuer's executive officers, directors and their respective affiliates will convert automatically into one share of Class A common stock upon any transfer, except for certain permitted transfers.

Remarks:

This amended Form 4 is filed solely to report that the Form 4 as originally filed on May 7, 2021 was correct as filed in connection with the exercise of two stock options and the issuance of the Issuer's Class B common stock in connection therewith; the disclosure above reflects the total number of shares of Class B common stock held after the exercise of the stock options, which Class B common stock was not converted to Class A common stock at such time, as was mistakenly reported in a Form 4 filed on May 7, 2021.
